Section 1371 Of Article 5. Standards From California Health And Safety Code >> Division 2. >> Chapter 2.2. >> Article 5.

. A health care service plan, including a specialized health care service plan, shall reimburse claims or any portion of any claim, whether in state or out of state, as soon as practicable, but no later than 30 working days after receipt of the claim by the health care service plan, or if the health care service plan is a health maintenance organization, 45 working days after receipt of the claim by the health care service plan, unless the claim or portion thereof is contested by the plan in which case the claimant shall be notified, in writing, that the claim is contested or denied, within 30 working days after receipt of the claim by the health care service plan, or if the health care service plan is a health maintenance organization, 45 working days after receipt of the claim by the health care service plan. The notice that a claim is being contested shall identify the portion of the claim that is contested and the specific reasons for contesting the claim. If an uncontested claim is not reimbursed by delivery to the claimants' address of record within the respective 30 or 45 working days after receipt, interest shall accrue at the rate of 15 percent per annum beginning with the first calendar day after the 30- or 45-working-day period. A health care service plan shall automatically include in its payment of the claim all interest that has accrued pursuant to this section without requiring the claimant to submit a request for the interest amount. Any plan failing to comply with this requirement shall pay the claimant a ten dollar ($10) fee. For the purposes of this section, a claim, or portion thereof, is reasonably contested if the plan has not received the completed claim and all information necessary to determine payer liability for the claim, or has not been granted reasonable access to information concerning provider services. Information necessary to determine payer liability for the claim includes, but is not limited to, reports of investigations concerning fraud and misrepresentation, and necessary consents, releases, and assignments, a claim on appeal, or other information necessary for the plan to determine the medical necessity for the health care services provided. If a claim or portion thereof is contested on the basis that the plan has not received all information necessary to determine payer liability for the claim or portion thereof and notice has been provided pursuant to this section, the plan shall have 30 working days or, if the health care service plan is a health maintenance organization, 45 working days after receipt of this additional information to complete reconsideration of the claim. If a plan has received all of the information necessary to determine payer liability for a contested claim and has not reimbursed a claim it has determined to be payable within 30 working days of the receipt of that information, or if the plan is a health maintenance organization, within 45 working days of receipt of that information, interest shall accrue and be payable at a rate of 15 percent per annum beginning with the first calendar day after the 30- or 45-working-day period. The obligation of the plan to comply with this section shall not be deemed to be waived when the plan requires its medical groups, independent practice associations, or other contracting entities to pay claims for covered services.
